You're right about the difference in the torque converter, where one locks and one does not. (PTO locks it.) In the reading, they claim the BCP raises idle to 1200rpm, same as PTO. (Or I THINK thats what I remember reading.) In my experience with both, BCP stays at around 900rpm and PTO is at 1200rpm (with no resistor modification). BCP will vary the idle speed automatically depending on electrical load. If you cold-start the truck and immediately flip the BCP on, it may go to a higher RPM initially, but usually backs down to the 900rpm (with no other electrical load). I like having both, depending on why I want high idle. If I were just doing it for the higher engine speed to prevent idle-associated problems, I'd probably do the PTO wire. My $.02 anyway.
